This is for some who face difficulty in reading NTFS partitions in Debian.
For a pen drive formatted in NTFS and whose device is sdb6
1. Mounting a NTFS partition:
First create a directory as 'mkdir a'
Second use this: sudo mount -t ntfs -o ro /dev/sdb6 a
Here in the second command - you are using the regular mount command but giving 2 options: 1. -t which tells that the 'type' is ntfs and -o ro : as an option telling it as read only.
Third you could use 'sudo sh' command and then cd or do anything to 'a' on the command mode or konsole mode.
To know in more detail as to what is NTFS-3G here you read it: http://en.wikipedia.org/wiki/NTFS-3G
Use synaptic to install ntfs-3g and I think that you got to use the latest and updated repositories to get it working.
Once NTFS-3g is installed - you can read write and execute what all you do the same way as you do it in the Gates world.
Cheers :) Hope this was of some help for some...
I am running out of time to catch my bus to work...
